SpaceX, NASA scrub Crew-11 astronaut launch due to weather (video)
CAPE CANAVERAL, Fla. — SpaceX scrubbed today's (July 31) launch attempt of the Crew-11 astronaut mission for NASA.
Launch officials called the scrub just over a minute before liftoff, due to a bank of cumulus clouds that appeared over in the skies over NASA's Kennedy Space Center here.
"Unfortunately, the weather is just not playing alongside with today's excitement on the launch for NASA SpaceX's Crew-11," NASA commentator Derrol Nail said during today's launch coverage.
"We could literally see the clouds kind of going over top of our heads, getting close to the pad, and the standoff area is a 10-mile radius around the pad for these dark clouds, cumulous clouds, and that is a safety factor," Nail added. "That is because you don't want to send a rocket through a tall cloud like that — that could generate some energy from the rocket passing through it."
SpaceX will try again on Friday (Aug. 1) at 11:43 a.m. EDT (1543 GMT). There's another chance on Saturday (Aug. 2) at 11:21 a.m. EDT (1521 GMT).
When it launches, Crew-11 will see a SpaceX Falcon 9 rocket take off from Launch Complex 39A at KSC. Atop the rocket is the company's Crew Dragon Endeavour spacecraft making its sixth flight, a reuse record for Crew Dragon vehicles.
The four crewmembers of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) and Oleg Platonov of Russia's space agency Roscosmos.
When it launches, Crew-11 will embark on a roughly 40-hour flight to catch up with the International Space Station, orbiting at a speed of about 17,500 mph (28,000 kph) some 248 miles (400 kilometers) above the surface of Earth.
As its name implies, Crew-11 will be the eleventh operational astronaut mission SpaceX has flown for NASA, through the agency's Commercial Crew Program, which sees NASA send astronauts to and from the ISS on private spacecraft.

Travelers Are Unknowingly Smuggling Invasive Ticks Into the U.S.
Here's an important tip for international travelers coming back home: Be sure to check for any blood-sucking creepy-crawlies attached to you. In a study out today, health experts warn that exotic, potentially disease-carrying ticks are regularly entering the U.S. by hitching a ride onto returning Americans. Tick scientists in Connecticut conducted the research, published Friday in the journal iScience. They detailed seven separate cases of non-native ticks entering the state via travelers in recent years, some of which carried possible germs. These introductions are likely happening all across the country, not just Connecticut, and are a serious public health concern, the researchers say. 'Each one of these ticks could potentially pose substantial health risk to the travelers as well as to the country,' study author Goudarz Molaei, a scientist at the Connecticut Agricultural Experiment Station's Center for Vector Biology & Zoonotic Diseases, told Gizmodo. 'If any one of them ends up released into the environment unintentionally, there is a potential they could start establishing populations and expanding.' Hot Tick Summer Is Here. Here's What You Need to Know and How to Stay Safe As part of their job, Molaei and his colleagues help identify ticks brought to them by the public, particularly human-biting and disease-causing ticks. And while most of these cases are caused by native species, they've occasionally come across nonnative ticks, too. Ticks and the diseases they spread have become a growing issue in the U.S., thanks partly to a warmer climate. These same conditions might also make it easier for invasive species to gain a foothold here, so the researchers wanted to highlight some of the exotic cases they've documented over the years. They describe seven nonnative tick introductions into Connecticut between 2019 and 2023. The ticks originated from Central America, Africa, and Europe. Two of the ticks, both members of the species Amblyomma mixtum, carried the bacteria Rickettsia amblyommatis. R. amblyommatis is related to known tickborne germs, including those responsible for Rocky Mountain spotted fever, and it's suspected to possibly cause disease in people as well. Outside of its human impact, A. mixtum ticks are dangerous to livestock, too, capable of causing massive infestations and spreading other diseases. Some of the other ticks they identified, such as Ixodes ricinus, also carry human diseases in their native environment, such as Lyme-causing bacteria. And just this month, Molaei and his team helped out on a new case of a nonnative tick within the state. The person carrying the tick became sick, and their doctors were at first perplexed on how to even deal with the situation, according to Molaei. Fortunately, the team directed them to a lab that could perform the proper testing, and the patient ultimately recovered. Molaei notes that since Connecticut isn't a huge travel hub, it's likely the risk of nonnative tick introductions is higher in other areas of the U.S. There are many places in the country where these and other exotic ticks could make a new home if given the opportunity, he added. Many states are also much less equipped to even detect these potential cases, according to Molaei, further raising the odds of new species and diseases sneakily establishing themselves in the U.S. This isn't a hypothetical risk either—it's already happened. In 2017, researchers in New Jersey discovered the arrival of the Asian longhorned tick (Haemaphysalis longicornis) to the area. Despite efforts to curtail its presence, the tick has since spread to nearly half of the country and has become a serious threat to livestock (though they can carry and spread human diseases as well). It's unknown how the Asian longhorned tick found its way here, though it may have ridden along with a human or animal traveler. Woman's 'Severe' Hearing Loss Caused by a Tick Stuck in Her Ear The researchers argue that more resources are needed to surveil and mitigate these invasive tick threats. These efforts should include increased monitoring of agricultural goods being brought into the U.S., along with improved education on identifying potentially exotic ticks. People in general should also be more aware of how to prevent and detect tick bites, especially when they're traveling. 'Travelers should remain alert. And they have to realize that apart from themselves being at risk of contracting tick-borne diseases when they are traveling, there are the unintentional consequences of these things that are arriving here,' Molaei said. 'A proper tick check is of importance, particularly before people get on a plane. And they have to carefully inspect their luggage and their clothing before they get on board.' For their part, Molaei and his team will continue to keep a close eye out for ticks, both native and exotic, in their state.

What Is Vibrio Vulnificus? Deadly Warm-Water Bacteria Is Spreading In The Southeast.
Almost a dozen people have died this year in the Southeast after contracting a flesh-eating bacteria called Vibrio vulnificus that thrives in warm water and can be exacerbated by hurricanes hitting the coast. An oyster on May 19, 2024. AFP via Getty Images Health departments in several states are warning residents about a mysterious and unusual rise in the bacteria after dozens of cases were confirmed across 11 states and at least nine deaths were attributed to an infection, with a tenth attributed to another vibrio species. At least 57 cases have been confirmed this year, according to Today, with the highest numbers in Louisiana (17), Florida (13) and North Carolina (7). Five people have died from Vibrio vulnificus infections in Florida and four have died in Louisiana, but it's still unclear how exactly the victims contracted the bacteria, which can be spread through infected sea water or through eating raw or undercooked shellfish. The bacteria thrives in warm water, meaning summertime is the most common time for infections, but one expert told NBC News the number of deaths is still high for this point in the season and another told Today that infections have been steadily rising for the last six to seven years.

Text 'Alerts' to (201) 335-0739 or sign up here : 'This is certainly not normal, that's one thing,' Jantarpreet Jutla, an engineering professor at the University of Florida, told NBC News. 'We haven't had that many cases early on in the summer for a very long time.' Vibrio are bacteria that naturally live in coastal waters and there are about a dozen different kinds of Vibrio that can lead to vibriosis infections, including vulnificus, which can cause severe and life-threatening infections. Vibrio bacteria thrive in warm seawater and particularly in brackish water—the mix of fresh and salt water found in estuaries and wetlands. How Are People Infected With Vibrio? People can get vibriosis after swallowing Vibrio or getting it in a wound. The Centers for Disease Control and Prevention says eating contaminated food is the most common way to contract a vibriosis infection, claiming it's responsible for more than half of the estimated vibriosis cases each year. Oysters and other shellfish are the most common carriers of Vibrio. People with open wounds can also be exposed to Vibrio through direct contact with seawater and some infections, like of Vibrio vulnificus, can lead to necrotizing fasciitis that kills the flesh around an open would, leading to the moniker "flesh-eating bacteria." There is no evidence that vibriosis is transmissible person to person. What Are The Symptoms Of Vibrio Vulnificus? Those who contracted the infection following the ingestion of raw seafood typically present with fever, chills, blistering skin lesions or dangerously low blood pressure. Wound infections typically come with fever, redness, pain, swelling, discharge and discoloration. Vibrio vulnificus infections are diagnosed by stool, wound or blood cultures. How Deadly Is Vibrio Vulnificus? A Vibrio vulnificus infection can lead to serious illness and need intensive care or limb amputation. About one in five people with the infection die, sometimes within a day or two of becoming sick, according to the CDC. Vibrio vulnificus infections tend to increase after hurricanes. Paul Gulig, a professor and member of the University of Florida Emerging Pathogens Institute, credits Hurricanes Katrina, Irma and Ian with increasing the visibility of the bacteria. When brackish hurricane waters flooded the streets, cases of the bacterial infection rose. Florida saw a total of 82 cases last year (up from 46 in 2023) after its busy hurricane season. The National Weather Service has predicted a slightly above-normal season for this year thanks to warm ocean temperatures. NOAA estimates there will be between 13 and 19 named storms this year, with six to 10 developing into hurricanes.

China Announces Breakthrough in Planned Moon Landing
China announced a major breakthrough in its planned moon landing mission as the East Asian power and the United States race to send humans back to Earth's natural satellite. China is moving toward its goal of landing astronauts on the moon by 2030. Meanwhile, the U.S.—the first and, to date, only country to land humans on the moon—has planned its crewed moon landing mission for mid-2027. However, the program's progress has faced challenges. Newsweek has contacted NASA via email for updates on its moon landing mission. During the height of the Cold War between the U.S. and the Soviet Union, NASA launched the Apollo program, which landed the first humans on the moon in 1969. A total of six lunar landing missions—with 12 astronauts—were conducted until the program ended in 1972. China is advancing several space programs as it pushes for supremacy in this domain. In addition to its moon landing mission, it has constructed a network of 16 space-enabling facilities in Latin America while operating a modern space station known as the Tiangong. The space race between China and the U.S. could define whether the 21st century is the Chinese or American century, Colonel Terry Virts, a former NASA astronaut, previously told Newsweek, warning that China could absolutely beat the U.S. back to the moon. The China Manned Space Agency announced that its manned lunar lander—named Lanyue, which means embracing the moon—successfully completed the first "comprehensive landing and takeoff test" at a test site in Huailai County in Hebei province, northern China, on Wednesday. Footage of the test shows the lander—a test vehicle—igniting its rocket engines while descending to the ground. Meanwhile, a ladderlike structure can be seen installed on the outside of the lander, which could be used by astronauts to exit onto the moon's surface. The event marked the first time China tested the "extraterrestrial landing and takeoff capabilities" of a manned spacecraft, according to the agency, which described the test as a breakthrough in the research and development of its manned lunar exploration program. According to Xinhua News Agency, the Lanyue consists of two modules—one for landing and the other for propulsion. It is designed to transport two astronauts between the moon's orbit and its surface. The lander serves as a base during astronauts' activities on the moon. The design of Lanyue is similar to that used in the Apollo program. The Apollo Lunar Module consisted of an upper stage—which contained a crew compartment and an ascent rocket engine—and a lower stage that had the landing gear and a rocket engine for descent. China is also advancing another moon mission aimed at building the International Lunar Research Station, a scientific experimental facility located both on the moon's surface and in its orbit. The project's two phases are scheduled for completion by 2035 and 2050, respectively. China's Global Times reported on Thursday: "The test validated key systems, including the lander's design, control strategies, lunar contact shutdown procedures, and interface compatibility between subsystems such as GNC (Guidance, Navigation, and Control) and propulsion." U.S. Transportation Secretary and interim NASA Administrator Sean Duffy outlined a plan to build a nuclear reactor on the moon on Tuesday: "We're in a race to the moon, in a race with China to the moon. And to have a base on the moon, we need energy." Besides the moon landing mission, U.S. President Donald Trump pledged to send astronauts to Mars, a goal supported by billionaire Elon Musk of SpaceX, who believes the moon "is a distraction."
